Answer:
Q'(-2 , 5)
Step-by-step explanation:
Note that:
1) When you are reflecting over the x-axis, you are changing the sign for the y.
2) When you are reflecting over the y-axis, you are changing the sign for the x.
In this case, you are reflecting over the y-axis. Change the sign of the x:
Q(2 , 5) ⇒ Q'(-2 , 5)
Q'(-2 , 5) is your answer.

The cosine for ∠A is
.
Option: A.
<u>Step-by-step explanation:</u>
From the given diagram,
Opposite = 8 ft.
Adjacent = 5 ft.
In trigonometry, the formula for cosine =
.
We are not given with hypotenuse. So we have to find the hypotenuse using Pythagorean Theorem ![hypotenuse = \sqrt{opposite^2+adjacent^2}](https://tex.z-dn.net/?f=hypotenuse%20%3D%20%5Csqrt%7Bopposite%5E2%2Badjacent%5E2%7D)
.
.
hypotenuse =
.
cosine =
.
Multiply
in both numerator and denominator,
The cosine for ∠A is
.
Answer:
<h2><u><em>
339/400</em></u></h2>
Step-by-step explanation:
4 squares with the area of 100 units ^ 2, in the last are only 39 blue.
100 * 3 + 39 = 339, your answer is 339/400
